part reflecting the DSF divestiture during 2008 offset to some extent
by growth in consulting during the first quarter.

operating margin of 23.5% benefited from a one-time gain on sale of

22.8% in the year-ago quarter reflecting the downturn in the economy,
but was in line with the Company’s objective on good execution of its
cost savings program.
